Signalling relay terminals K11, K12, K14
If a fault occurs, the signalling relay (changeover) is triggered. The
switching conditions can be programmed as required.
Table 18: Default setting of the signalling relay
X Use the above table to configure contacts K11–K12 or K11–K14
as make or break contacts under PNU C33.
After a fault has occurred, the associated fault message is retained
even after the voltage supply is switched off. The fault message
can be displayed again after the voltage has been switched back
on. However, the inverter is reset when the device is switched off,
i.e. the fault message will not be signalled on the terminals of the
signalling relay after the inverter is switched back on.
When the signalling relay output is configured as a break contact
(default setting), it is important to remember that there is a delay
from the time the supply voltage is switched on until the AL output
is closed, and that a fault message for the AL output therefore
appears for a short time after the supply is switched on.

If however, the fault signalling is to be retained even after
the inverter is switched back on, a latching (self maintai-
ning) relay should be used.
